Adaptive facades can ensure step-change progresses in the energy efficiency and the use of renewable energy while improving the comfort of the occupants. Therefore, the purpose of this structured interview is to assess advantages, disadvantages and future expectations considering the adaptive facades. This work is a part of actions of The COST Action TU1403 Adaptive Façade Network. The objective of this report is to gain an understanding of how experts currently define adaptive façade systems, which simulation tools they use, the major strengths, weaknesses, opportunities and treats of adaptive façade systems, key performance indicators they use and their vision for the future of adaptive facades. With this information gathered, it is anticipated that adaptive façade professionals will carry on assessment of adaptive facades. A qualitative study design was employed, using semi-structured interviews. Interviewees working in academia and practice were selected. The interviewees represented the range of possible adaptive facade professionals, from researchers and designers considered optimization in the assessment of adaptive facades. Also, every interviewed expert was asked to approve their responses and add any additional comment to their answers. [less ▲]

Adaptive facades are performance based envelopes that are able to respond dynamically to climatic conditions. One of the recognized adaptive façade technologies is electrochromic glazing. However, very few studies evaluated the performance of electrochromic glazing on the building level. Therefore, we selected a case study of a certified educational building with a nearly zero energy building performance that includes an electrochromic facade. The overall aim of the research is to understand the performance requirements of electrochromic glazing and its overall contribution to energy saving s and thermal and visual comfort improvement. The performance of the Swiss International School in Dubai was analyzed based on interviews with the design and build team, monitored data and post occupancy evaluation. A systematic process mapping took place to review the performance indicators, simulation tools and team responsibilities during the design, construction and operation stages of the building. The paper identifies the key performance criteria of electrochromic glazing in relation to energy and comfort. Finally, we assess the significance of using electrochromic glazing from a technical point of view and share the learned lessons for architects and facade engineers [less ▲]

According to Jennifer A. Peeples, the “toxic sublime” refers to “the tensions that arise from recognizing the toxicity of a place, object or situation, while simultaneously appreciating its mystery, magnificence and ability to inspire awe”. As an alternative to the “technological sublime”, which creates awe through the contemplation of human efforts to master the environment, it urges us to consider the negative and noxious aspects of such endeavours. Through her analysis of Edward Burtynsky’s “Manufactured Landscapes”, Peeples introduces a new form of sublime aesthetics, which may also be used as a valuable trope in the study of the relationship between literature and our physical environment. My goal in this study is to extend such considerations to the recent history of American literature, using examples such as Rachel Carson’s “A Fable for Tomorrow” (1962), which describes the invisible “lethal film” made of “systemic insecticides” that converts natural species into carcinogenic poison, thus depicting landscapes as intoxicated “places of beauty” that no longer symbolise human abilities to dominate the environment but rather their lack of control over it. Likewise, in Don DeLillo’s novel White Noise (1985), the protagonist Jack Gladney experiences his daughter’s “utterance” of the car brand “Toyota Celica” as “beautiful and mysterious”, which “str[ikes] [him] with the impact of a moment of splendid transcendence”. Gladney then proceeds to relate his family’s “garbage” to his relatives’ selves as it is a “sign[] of [their] deepest nature”. Jack’s approach to human waste shows that what Cynthia Deitering defines as the “toxic consciousness”—the general awareness of the existence of toxicity in the landscape—is to be associated with the protagonist’s idea of “consumer consciousness”. Indeed, the term toxicity can also metaphorically refer to the “poisoned” nature of our relationship to and perception of specific places, objects, or situations. The viewer in national parks, for instance, tends to see the “sublime landscape” as a “series of picturesque scenes”, which allows him to consume the scene as an “object of artistic consumption”. Such examples point to different but related ways of examining distinct forms of toxicity that characterise our relationship with our physical environment. They also prompt us to examine the problematic nature of technology and progress while dealing with the elusive and paradoxical nature of the technological sublime. [less ▲]

In many applications, and in systems/synthetic biology in particular, it is desirable to compute control policies that force the trajectory of a bistable system from one equilibrium (the initial point) to another equilibrium (the target point), or in other words to solve the switching problem. It was recently shown that, for monotone bistable systems, this problem admits easyto-implement open-loop solutions in terms of temporal pulses (i.e., step functions of fixed length and fixed magnitude). In this paper, we develop this idea further and formulate a problem of convergence to an equilibrium from an arbitrary initial point. We show that this problem can be solved using a static optimization problem in the case of monotone systems. Changing the initial point to an arbitrary state allows to build closed-loop, event-based or open-loop policies for the switching/convergence problems. In our derivations we exploit the Koopman operator, which offers a linear infinite-dimensional representation of an autonomous nonlinear system. One of the main advantages of using the Koopman operator is the powerful computational tools developed for this framework. Besides the presence of numerical solutions, the switching/convergence problem can also serve as a building block for solving more complicated control problems and can potentially be applied to non-monotone systems. We illustrate this argument on the problem of synchronizing cardiac cells by defibrillation. Potentially, our approach can be extended to problems with different parametrizations of control signals since the only fundamental limitation is the finite time application of the control signal.

Le travailleur du futur et la loi A quoi ressemble le travailleur de demain dans un monde où règnent toujours davantage les technologies de l’information ? Cette question est envisagée sous deux angles. Tout d’abord, l’économie numérique a fait naitre de nouvelles formes de production et d’emploi, telles que « l’économie des plateformes » (Uber, Deliveroo, ….). Celle-ci présente divers atouts pour les entreprises et pour les travailleurs, notamment en termes de flexibilité, mais elles est aussi la source de nouvelles formes de travail précaire. Le travailleur de demain est-il un travailleur du numérique sans protection sociale ? Le deuxième angle est celui du travailleur hyperconnecté. Faut-il envisager de créer un droit à la déconnexion ?

Comme les écosystèmes dulçaquicoles, les écosystèmes marins sont soumis à une pression humaine croissante qui altère la qualité de l’eau et les communautés aquatiques. Près de 98 pourcents de l’eau de notre planète bleue est contenue dans les océans qui constituent le réceptacle final de tout ce que nous rejetons comme déchets (volontairement ou non). Moins accessible, les océans sont méconnus, souvent oubliés ou négligés et considérés comme une zone inépuisable et où tout se dilue ; actuellement encore 80% des eaux usées sont rejetées en mer sans traitement préalable, à peine 2 % des surfaces marines sont protégées. La Méditerranée est particulière à plus d’un égard, bassin de concentration, de faible surface (1% des océans) abritant pourtant plus de 10% de la biodiversité mondiale. Cette petite mer est un modèle pour les océanographes : en mesurant ce qui s’y passe, nous pouvons prédire ce que se déroulera à court ou moyen terme dans le reste des océans. Le laboratoire d’Océanologie est activement impliqué depuis une quinzaine d’années dans la mise au point d’indice de la qualité des masses d’eau côtières. Ces indices sont construits sur base des connaissances du milieu (variations naturelles), par la mesure des niveaux de contamination et des effets (observation et contamination en mésocosme) de cette pollution sur les communautés. Nous avons développé et validé des indices biologiques (PREI : Posidonia Rapid and Easy Index, ICAR Indice Caulerpa cylindracea ; espèce envahissante), de pollution (TEPI : Trace Element Pollution Index, TESVI : Trace Element Spatial Variation Index), de qualité paysagère (LIMA LIttoral MArin) … Ces indices sont utilisés actuellement dans le cadre de la DCE (Directive Cadre Eau), la DCSMM (Directive Cadre Stratégie pour le Milieu Marin) et dans des réseaux de surveillance en Méditerranée, ils sont un relais et un moyen de communication entre les scientifiques et les politiques, les gestionnaires. L’exportation et l’apprentissage de l’utilisation de ces indices sont un atout pour une gestion globale de l’eau à l’échelle de la Méditerranée. Leurs applications sur l’ensemble de la façade méditerranéenne ont, entre autre, mis en évidence l’impact positif de l’application de directives européennes en matière de gestion des eaux par rapport aux côtes de Nord de l’Afrique.

Regenerative design holds great promise for a new era of sustainable and positive impact architecture, sparking considerable interest among architects, building professionals and their clients. Until now there are no green buildings with an overall positive impact on environment and health. In this regard, the professional and scientific potential of regenerative architecture can only be fully realized by the setting a design framework that guides designers during projects design, construction and operation. This book introduces readers to key concepts of circularity in the built environment, highlight best practices, introduce opportunities to create value learn from real cutting edge case studies. In this book, we present a novel framework for regenerative building design that can be applied to future constructions based on professional expertise and exposure, towards healthy, resource efficient and green buildings in the AEC industry. We compare four state of the art buildings to address the critical principles, strategies and steps in the transition from the negative impact reduction architecture to the positive impact regenerative architecture, utilizing life cycle analysis. The case studies analysis and comparison can serve as an inspiring eye opener and provide a vision for architects and building professionals in the fields of high performance buildings, resource centered thinking and regenerative architecture.

Lorsque Spacewar!, considéré comme un des premiers jeux vidéo, voit le jour en 1962 dans les salles du Massachussets Institute of Technology, il marque le début d’une longue relation entre ce médium et la science-fiction. À l’heure où l’informatique est encore fort peu micro, la thématique spatiale que ce précurseur exploite présente en effet un avantage certain : celui de déployer à l’écran un « espace dont la principale caractéristique est le vide [...] un lieu qui exige moins de puissance de calcul » (Triclot, 2011). De l’émergence de cette culture hacker dans les années 1960 à la production actuelle, le jeu vidéo a constamment puisé dans les ressorts propres à la science-fiction – que ce soit les accents cyberpunk d’un Deus Ex : Human Revolution (Square Enix, 2011), l’uchronie d’un Wolfenstein : The New Order (Bethesda Softworks, 2014) ou encore la dystopie constitutive d’un Bioshock (2K Games, 2007). Cette richesse spécifique a pourtant été peu interrogée. [less ▲]
